commit 5edb24bcbbf99274cde2ca74dbbad546630aeedc Author: Aaron Durbin adurbin@chromium.org Date: Fri Nov 8 17:37:48 2013 -0600
baytrail: fix fadt structure for gpe0 block
The gpe0 block's size was being misreported. Correct the gpe0 size and use make the FADT fields be more robust instead instead of hand calculating fields that are the based on the same size.
This change correctly enables GPE events in the kernel. Confirmed this by using iotools read the gpe_cnt register.
BUG=chrome-os-partner:23505 BRANCH=None TEST=Built and booted. Confirmed EC's GPE event is enabled (but still not working).
